Parsing a network address string

Question

I am using python 3.5 and have a network address string like the following:

tcp://10.1.2.3:45678

I want to parse this string and extract the protocol, the ip address and the port number.

I know I can do this very easily with a string split or regex, however I was wondering if there is a python package or module that does this. I am sure that there is a specification for these string which defines them, hence I am interested in a python module instead of using regex or string parsing.

You are looking for urllib.parse.urlparse:

In [1050]: import urllib

In [1051]: urllib.parse.urlparse('tcp://10.1.2.3:45678')
Out[1051]: ParseResult(scheme='tcp', netloc='10.1.2.3:45678', path='', params='', query='', fragment='')

In [1052]: url = urllib.parse.urlparse('tcp://10.1.2.3:45678')

In [1053]: url.scheme
Out[1053]: 'tcp'

In [1054]: url.netloc
Out[1054]: '10.1.2.3:45678'

In [1055]: host, _, port = url.netloc.partition(':')

In [1056]: host
Out[1056]: '10.1.2.3'

In [1057]: port
Out[1057]: '45678'
